NFL Media Insider Ian Rapoport reported Tuesday that per the terms of Smith's union-league negotiated settlement, his suspension could be shortened by a game or two based on good behavior -- which he has exhibited -- according to two sources who have seen the agreement.

ProFootballTalk first reported the potential reduction.

If the suspension is reduced, Smith could return as soon as after the Niners' Week 8 bye to face the St. Louis Rams on Nov. 2.

With a plethora of other injuries on the defensive side of the ball, getting their best pass rusher back on the field would be a huge boon for a Niners team battling for playoff positioning in a tough NFC.
